Authorities have not yet said if Clark's arrest is connected to the case of Kiera Lanae Bergman, who has been missing since Aug. 4.

Bergman left her home without her purse, her wallet, her keys or extra clothes. Bergman's roommate and best friend, Destiny Hall-Chand, told KPHO-TV that Bergman did not come home after sending Hall-Chand an odd text message.

Police said Bergman is 5-3 and weighs 145 pounds, but officials didn't provide a description of what she was last seen wearing. Anyone with information on the whereabouts of Bergman is asked to contact the Phoenix Police Department's Missing Persons Unit at 602-534-2121.
